Why does WB Animation keep failing on Cartoon Network? Could it be that the newest version of Batman made no logical sense. Lacked the fun of Batman: Brave and the Bold? The abrupt move to CGI for no reason? Bruce Timm is old and out of it and no new blood has been pumped in? Questions can be asked over and over, but for now Beware The Batman has been pulled from DC Nation's line-up until January. If you may remember this happened to both Green Lantern: The Animated Series and Young Justice before the shows were cancelled.
Let us not forget ThunderCats either.
You usually might want to have a cartoon series going on concurrently as a new video game comes out based on the same character, but hey WB do whatever you want. Cartoon Network programming astonishes with putting the show only on Saturday mornings instead of when school gets out so kids can see it on a daily basis.
Something tells me CN wants these shows to fail. Why? Unknown, maybe they want their own content on air and don't care to keep re-treading the DC and Hannah Barbara Library.
